You are right; all of the Apostles were Torah Observant Jews. Their Master taught that till the end of time the Torah was to be strictly observed right down to the last detail: Matthew ch. 5. Romans 6 has been twisted and misunderstood. The entire chapter is an exhortation to stop all sin. And Sin is defined as failure to observe and do the Torah. When it says “we are not under the Law, It means that we are not under the Condemnation of the Law.

But it never meant that anyone could whatever they want to do. The Torah is Perfect, and eternal. Return to Torah and live. All of its ways are pleasant and it is filled with every good thing.
